2. 1. This is just a number 10 to power minus 6 and that value is 0.000001
2.
Note : J is the number of aggregated component carriers in a band or band combination
This Value means sum of all carriers & In NR, carrier is the center frequency of the spectrum
being used to transmit the NR signal. More spectrum, higher the speed
3.
This means is the maximum number of layers ( This means if gNB is transmissiting two antenna to UE,
2X2 or 4X4 , it means how many layers your transmit from gNB to UE)
4. This value means the maximum modulation order Modulation scheme
QPSK – 2 bit
16 QAM- 4 bit
64 QAM – 6 bit
256 QAM – 8 bit
5 . This is the scaling factor
.
The scaling factor can take the values 1, 0.8, 0.75, and 0.4

3. 6. 948/1024 , I didn’t find anything about this any where, seems its just a number to make it in mbps
7. This is the average OFDM symbol duration in a sub frame for numerology
Note that normal cyclic prefix is assumed
μ Numerology 0,1,2,3,4,5
8. This is the maximum RB allocation in bandwidth BW with numerology μ ,
Maximum transmission bandwidth configuration
The maximum transmission bandwidth configuration NRB for each UE channel bandwidth and subcarrier spacing
is specified in Table 5.3.2-1.
12 This is just number which is multiply by number of PRB

4. 1 This is just a number
0.14, for frequency range FR1 for DL
0.18, for frequency range FR2 for DL
0.08, for frequency range FR1 for UL
0.10, for frequency range FR2 for UL
Last calculation is 1 minus overhead
Note: Due to higher band in FR2 DL overhead and UL overhead is higher.

5. Let’s calculate 5G Throughput
Carriers = 1
Layers = 2
NR Data Rate = 10-6 * 1 * 2 * 6 * 1 * (948/1024) * (273 * 12) * (14 * 21) / 10-3 * (1 - 0.14) = 876.4 Mbps
Modulation = 64QAM= 6 bit
Scaling factor = 1
Band = n1 Maximum number of RB
Sub carrier spacing = 30 KHz (Numerology = 1)μ
Overhead = 0.14

6. Let’s calculate in another way
1. Layer : 4
2. Modulation 256 QAM = Modulation order 8
3. Scaling Factor =1
4. Numerology = 0
5. Bandwidth = 50 Mhz
6. Resource Block= 270 from bandwidth and numerology
7. Overhead = 0.14 for DL
0.000001 1 4 8 1
